It's my eXtra HYPHENation file . :)

Up in that xhyphen.tex

Thanks for this info, but my problem still remains.
\useencoding[win] is changing the input encoding. So I should use it before 
there is any text-input.
In my understanding this should be before my hyphenation file (xhyphen.tex) 
is input.
When I do this, I get again the hypenation error that complains that the 
word to be hyphenated
  must contain only letters and hyphens.
So, using the AER-Font doesn't change anything in this situation.
Only when I use this \useencoding[win] after the hyphenation is done, all 
seems to work.

My concern is that when I hyphenate \hyphenate{au\-ßer\-dem} what it will 
be hyphenated like.
Will TeX now have "au\-ßer\-dem" in its hyphenation table or 
"au\-SSer\-dem"? Will an "außerdem"
after the change to the win-input-encoding be recognized as the one 
hyphenated before the change?

Not really, but thanks for the try.
